To all whom itmay concern Be it known thatI, Gnonon LEWIS HOGAN, of the cityof New York, N. Y., United States ofAmerica, and temporarily residing at 56 Sherbroo-ke street west, Montreal, Province of Quebec, Canada, have invented certain new and useful Improvements in-Vapor- Burning Apparatus; and I- do hereby declare that the following is a full, clear, and exact description of the same.

My invention relates to apparatus such as lamps or stoves in which Volatile fuel is used for the production of light, heat or power and wherein air is first mixed with the efficiency of the apparatus for the reason that minimum suctlon 1s necessarv in its 7 i the fuel and the mixture then conveyed to the ignition point, the proportion of such mixture being regulated and the travel of the same controlled by intermediate devices to which this invention has particular reference.

An object of the present invention is to provide a vapor burning apparatus which is of a simple and inexpensive construction,

a one advantage being the unimpeded interior passages which present a practically straight travel for the vapor, etc, thus reducing the resistance offered to the latter and increaslng operation. I

a A further object "is to improve the general construction of this type of apparatus by firstproviding a simple device for regu- For full comprehension, however, of my" invention reference must behad to the accompanylng drawings forming a part of this specificatlon in which similar reference low standard m having the gallery a sup characters indicateahe same parts and y yw H I a Figure 1 is avertica'l section ofa vapor burning lamp constructed acoording'to' my invent on Fig. 2 is a side elevation of the lamp. in'use f and supported upon a stand; 3' is horizontal section on line 3 Fig. 1; Fig. 4! is a perspective, view ofthe compensating device;-Figs. 5 and 6 are horizontal sections on-lines 5-5 and 6@ respectively, Fig. 1; and Fig. 7 isla detail section of a modifiedform of my invention.

By way of example I have illustrated a vapor burning lamp in the drawings and will now describe -my' invention with reference to the samel The lamp is of the type embodying a carbureter consisting preferably of a drum or casing b inclosing aliquid fuel absorbing block or equivalent 0 held in place by lugs d upon the interior of the'casingiand having air passages e therethrough. The end walls f of the casing present chambers g and h, respectively, the chamber 9 or air chamber has an opening through the top thereof within which is screwed a fitting 21 presenting oneor more air vents j. a

The burner of the lamp consists of a fiared'hase Z0 resting loosely uponaspinning Z solderedor otherwise secured to the fitting i and overhanging the top of the casing b. Extending from the base 76' is a tube or 1101- ported thereby near the top with the chimney oand mantleo'.

The base k of the burner is provided with inlets 37 through which the air enters and passes through the vent-s y, to the air chamher 9 and from where it is distributed,by a plate 9, tothe passages (Z in the absorbent blocln'and so passesto the chamber 7L. As thelair passes through the passage clit becomes charged with the liquid fuel and collects in the lowerchainber h' inthe form of This'passage is preferably formedinthe' block a and in line with the fitting 11. The tube r extends from the passage 8 and passes loosely through the fitting i to a point Within the hollow standard m.

In order to mix air with the vapor in the tube 7" I have formed one or more vents or slots 6 near the bottom of the latter and as a portion of the air from the chamber 9 passes down through the passage 8 it will enter these vents and mix with the vapor. To control the quantity of air entering the tube and therefore regulate the proportion of the mixture in the tube 1 I have arranged the latter so that it is free to be moved 1ongitudinally and in this way when a small amount of air is required the tube is moved to bring the vents away from the top or air inlet end of the passage and when a greater quantity of air is required the tube is moved up and the vents therein brought nearer to the top ofthe passage. This regulation of the air to the tube 1' is made more effective by reducing the lower end ofthe passage 8 to closely inclose the tube so that when-the latter is lowered the vents 25 are closely adjacent to the sides of the passage and the approach of air thereto further obstructed. To obtain this effect the passage may be tapered but I prefer to form it as shown in the drawings wherein I have formed a shoulder u at a point about midway of the passage and. at such a height, relatively to the tube when in its lower position, that the top of the reduced portion is about level with the tops of the vents t in the tube. To prevent crumbling of the absorbent block I have provided a bushing 41 in the passage 8 which is preferably held in position by a lateral flange 20 extending into the block.

The tube a" is longitudinally moved by a handle 2 which is secured to the tube and ex- .tends upwardly 'at the side of the latter,

loosely through the fitting 2' and through the base 70 of the burner where it is preferably bent to form a hand piece. The tube is yieldingly held in any adjusted position by a spring detent 4 carried by the fitting z and passed through the latter to engage with the tube while, in like manner, the position of the handle 2 is yieldingly maintained by a spring 5. I

Between the bottom of the fitting 2' and the" top of the passage 8 is loosely located a washer 6 through which the tube r and the handle 2 passes, while upon the tube, at a desired polnt near the lower end thereof, are oppositely located pins or projections 7 which at a certain point in the upward travel of the tube, engage with the washer 6 and cause the latter to close the air vents j and so stop the operation of the lamp.

Secured within the base 70 of the burner and at a point between the air inlets p and the airvents j in thefitting z, is a horizon- -member 15 in the chamber tally disposed perforated plate 8 which acts as a bafiie plate and protects the interior of the lamp from disturbances due to high winds, etc., outside the lamp and in this Way a steady current of air is directed through the vents j and fluctuations in the flame obviated. 7 I

lVhen the lamp is first lighted] the absorbent block will give off an abundance of fuel and the vapor in the chamber 71. will ac cordingly be very rich and require to be mixed with a considerable quantity of air whereas later on, as the fuel supply becomes depleted, the vapor will not be so rich and need only a small amount of air. To compensate for this difference in condition of the vapor I have provided a device which is located in the vapor chamber and consists of a disk 9 or sheet of soft wood or other absorbent material such as fiber, which is suspended below the. block 0 by a strip 10 of springy metal secured at one end to the wall of the chamber and having the disk fastened to its opposite end. Then the block 0 is being charged with fuel the disk 9 will .also become saturated and expand out of its normal state to a position closer to the block 0 as seen in dotted lines Fig.1, and partially obstruct the passages 6', so that when the lamp is first lighted the flow of vapor from such passages will be reduced but the operation of the lamp is not interfered with because only a partial supply of the rich vapor is necessary and as upon raising the tube r to allow the air to enter the same a mixture in proper proportion and quantity is con veyed to the burner. As the fuel in the block 0 becomes depleted it will be proportionately exhausted from the disk 9 permitting the latter to assume its normal position and not obstruct the passages cl and inthis way a fuller supply of a weaker vapor is carried to the tube 1" and thelatter lowered to restrict the air supply thereto as may be desired.

The burner is of the usual construction with the exception of a chamber 11, having air vents 12, formed below the gallery 72, around the outside of the standard m and communicating with the chimney. The chamber 11 is provided with an aperturela through which a lighted match or other flame may be inserted, the flame rising at the side of the mantle and causing a suction which draws the vapor up through the standard m and ignites the same. A minimum amount of suction is required which is due to the straightand practically unimpeded passages provided for the-air and vapor by my improved construction. In orderv to close the aperture Li I have provided a to slide over such aperture, the member preferably comprising an inner ring slid which is adapted H As is usual in lamps of this type the burner is removable and in this instance the. burner is, as above mentioned, resting E loosely upon the spinning Z and :held in position by the baflie plate 8 which encircles the tube r. The base 7c of the burner is adially ot-t d as at 20 and the bat Plate L 8 is correspondingly slotted to accommodate the handle 2 and avoid interference with the latter when the burner is removed.

The handle 2 may be of wire but in my preferred construction it is formed of small bore pipe and engages the tube 1' at a point just above the vents t, that is to say at a point below the normal level assumed by the vapor in the tube which is substantially above the horizontal center of the block 0. One end of the handle isloosely passed through the tube 7 and turned up as at 22 and has a bulb 25 attached at its opposite end and by pressing the bulb a forced draft can be produced in the tube 1" which, commencing below the level of the vapor, positively 'orces the same up into the burner.

In Fig. 7 I have shown a modification wherein my invention is applied tora stove, the pipe 24 leading to 'theburner of the latter. The operation of the stove is the same as the lamp with the exception that the tube 9" is below the fitting 2' and the top of such tube engages the washer 6 to close the inlet in the fitting while the handle 2 extends up through the fitting and is yieldingly supported by the spring 5 and in turn supports the tube.
